The only way I can think of of hacking that would cause any real damage is getting into Badspot's computer or getting into the masterserver, of course, eitherway they would just be repaired unless it was Badspot's computer.
No way to infiltrate a clan unless the higher ups get life in jail or killed, but then it would fall apart anyways.
Unless you know, your like probuilder and try to convince people that you are god.
Also the server host could just delete his or her banlist, thus letting them be unbanned.
Also theres like no way to get super admin on someone elses server. Also you cant ban super admins(i.e host?) and they could just ban you if they had IGSO.
Overall your idea fails.
